EKL Key word to set the faces in the Probing Slot cycle

Hello, i would like to set by EKL some input to a probing slot cycle .

No problem to set the TOP, PART and Planes, but i cannot set the FACES .

I tried to use the key word "ProbingSlotFaces" like it is wroten in the help but it doesn't work properly .

Can you confirm me it is the good key word to use ?

Do we have to manage this input on a specific way because we need 2 input ?

Thank you in advance for your help.
